Most Helpful Positive Review BEST 9mm carbine comp on the market. period.
No, it’s not cheap. But in my opinion, I will not waste my money buying something that does not perform as well as another product just to save a few bucks. If you are looking for the absolute cutting edge in innovation and performance, look no further. My #1 problem with PCC’s are vertical muzzle rise, and since I am simply neither patient enough nor flat out willing to deal with the ATF as far as getting tax stamps for AOW or SBR to put a VFG or butt stock on my PCC to help account for muzzle rise, I bought this. I bought it originally from the Walker Defense Research website, but saw no rev...

NERO 9 is amazing!

by David Lightfoot, Verified Owner from FL, United States Written on June 27, 2025
This is worth every penny I paid for it and will be buying one for my 5.56 and 7.62 rifles as well. Installed on my Smith & Wesson FPC 9mm and instantly feel the difference in recoil and muzzle movement. Follow up shots are so much faster! Buy it…you won’t regret it.

Works Well-Looks Good

by Archer, Verified Owner from RI, United States Written on March 15, 2025
I installed this on an LWRC IC-9 which arguably has minimal recoil and muzzle rise. Like so many I like personalizing my weapons and improving performance. The comp comes with one crush washer and nothing else. Instead of the crush washer I opted for a .004" shim and a drop of loctite.

The result: The compensator works. It allowed me to keep tighter than usual groups while rapid firing. And it looks like no other comp so the "uniqueness" is appreciated.
Pros:
  • Works as advertised
Cons:
  • None
Best Used for:
  • Tighter groups
  • Tighter groups on target
Would recommend: Yes

Beyond Expectations

by 9mmfan, from ID, United States Written on February 11, 2022
I have tried a wide assortment of compensators for 9mm and this is the first one that does what it says it is going to do. It may not be the most attractive unit out there (I like the ray-gun look!) but form follows function and it does a terrific job at mitigating and reducing muzzle rise and recoil. I received the unit and within 15 minutes had it installed and tested on an 8" barrel 9mm pistol with brace. Way too much fun. Can't recommend it highly enough! Well worth the price.
Pros:
  • Does what it claims
  • really like the look
Cons:
  • None
Would recommend: Yes

Perhaps worth the cost

by birdman, Verified Owner from CO, United States Written on January 8, 2022
Helps with up/down force and recoil. Barrel stays steady, easily allows next shot. Looks great, no bad-a$$ actually. 4 stars because it won't stay in position without pinning on my Rugar Charger 9mm anyway. Yes I used the crush washer and perhaps with a high heat lock thread it may solve this, but I don't like to use the stuff if I don't absolutely have too.
It is very loud, you won't be able to hide after a shot. Don't know why it is so expensive but I did order another one for my AR-15 so I'll let you know how it stay's in place. Perhaps thats why it's so expensive, they know you will pay for it if you care that much about looks.
Pros:
  • Looks and dampening
Cons:
  • Very expensive, very loud
Would recommend: Yes
